3. Cervus taevanusy Blyth (Journ. A. S. B. xxix. p. 90), from 

 Formosa (PL XVI.). 



4. Cervus swinhdii, sp. nov., from Formosa (PI. XVII.). 



Our single male specimen of Swinhoe's Deer stands about 

 2 feet 8 inches in height, and presents the general appearance of a 

 small Deer of the Sambur group (Rusa). The head, neck, and fore 

 legs are greyish black, growing more rufescent on the back, and 

 passing on the rump and hind-quarters into a deep chestnut. The 

 tail is rather long and very bushy, and composed of grizzly blackish 

 hairs. The inside of the thighs and belly beneath are fawn-colour, 

 passing on the inside of the legs into pale ochraceous. The animal 

 appears to be in about its second year. The present horns have 

 been injured whilst growing, and are much broken.

We have named this interesting new form after its discoverer, 

 Mr. Edward Newton, a gentleman who has recently visited Mada- 

 gascar, and whose zealous efforts have very materially forwarded our 

 knowledge of the ornithology of the East-African Archipelago. 



The genus Tglas is nearly alhed to Hypsipetes, but differs in the 

 beak being decidedly stronger, broader, and more inflated ; in the 

 longer wings, which in Hypsipetes do not reach to the middle of the 

 tail ; in the tail being proportionally shorter ; and in the rictal 

 bristles being much more developed. The under tail- coverts are very 

 long. The iris is yellow — a colour not found hitherto in the genus
